Dmitry Torokhov 4200e831e4 Input: of_touchscreen - switch to using device properties
Let's switch form OF to device properties so that common parsing code could
work not only on device tree but also on ACPI-based platforms.

Dmitry Torokhov 7c494375b7 Input: improve parsing OF parameters for touchscreens
When applying touchscreen parameters specified in device tree let's make
sure we keep whatever setup was done by the driver and not reset the
missing values to zero.

Sebastian Reichel b98abe52fa Input: add common DT binding for touchscreens
Add common DT binding documentation for touchscreen devices and
implement input_parse_touchscreen_of_params, which parses the common
properties and configures the input device accordingly.

The method currently does not interpret the axis inversion properties,
since there is no matching flag in the generic linux input device.
